Description

本発明は、低熱膨張線状体の製造方法、特に、低熱膨張線状体に連続的な長い（数十ｍ〜数Ｋｍ）めっきを施す低熱膨張線状体の製造方法に関するものである。   The present invention relates to a method for producing a low thermal expansion linear body, and more particularly to a method for producing a low thermal expansion linear body in which continuous long (several tens to several kilometers) plating is applied to a low thermal expansion linear body.

従来、低熱膨張線状体の製造方法としては、下記の特許文献１に示すような方法が提案されていた。   Conventionally, as a manufacturing method of a low thermal expansion linear body, the method as shown in the following patent document 1 has been proposed.

図５は従来の低熱膨張線状体の製造方法を示す図である。   FIG. 5 is a diagram illustrating a conventional method for producing a low thermal expansion linear body.

この図に示すように、（１）まず、図５（ａ）に示すように、負の線膨張係数を有する繊維材料１０１に撚りをかけたものを芯材として用意する。（２）次に、図５（ｂ）に示すように、その繊維材料１０１をめっき槽１０２に浸して、正の線膨張係数を持つ導電性材料１０５をめっきする。つまり、めっき槽１０２では、電着させようとする金属１０３と負の線膨張係数を有する繊維材料１０１を電解液１０４中に浸す。次いで、この繊維材料１０１を陰極とし、金属１０３を陽極として直流電流を流すと、図５（ｃ）に示すように、負の線膨張係数を有する繊維材料１０１上に正の線膨張係数を持つ導電性材料１０５をめっきすることができる。
特開２００６−０８５９１５号公報 As shown in this figure, (1) First, as shown in FIG. 5A, a fiber material 101 having a negative linear expansion coefficient is twisted and prepared as a core material. (2) Next, as shown in FIG. 5 (b), the fibrous material 101 is immersed in a plating tank 102, and the conductive material 105 having a positive linear expansion coefficient is plated. That is, in the plating tank 102, the metal 103 to be electrodeposited and the fiber material 101 having a negative linear expansion coefficient are immersed in the electrolytic solution 104. Next, when a direct current is passed using the fiber material 101 as a cathode and the metal 103 as an anode, as shown in FIG. 5C, the fiber material 101 having a negative coefficient of linear expansion has a positive coefficient of linear expansion. The conductive material 105 can be plated.

しかしながら、上記した低熱膨張線状体の製造方法では、めっき槽１０２の幅寸法に制限されて、長い連続した導電性を有する低熱膨張線状体を製造することはできなかった。   However, in the above-described method for producing a low thermal expansion linear body, the low thermal expansion linear body having a long continuous conductivity cannot be produced due to the limitation of the width dimension of the plating tank 102.

以下、本発明の実施の形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail.

図１は本発明の実施例を示す低熱膨張線状体の断面図である。   FIG. 1 is a sectional view of a low thermal expansion linear body showing an embodiment of the present invention.

この図において、１は負の線膨張係数を有する芯材としての繊維材料であり、例えばザイロンまたはダイニーマを用いることができる。２はその繊維材料１にめっきされる正の線膨張係数を持つ導電性材料であり、例えば銅が用いられる。   In this figure, 1 is a fiber material as a core material having a negative linear expansion coefficient, and for example, xylon or dyneema can be used. 2 is a conductive material having a positive linear expansion coefficient plated on the fiber material 1, and copper is used, for example.

The figure which shows the manufacturing apparatus of a body, FIG. 4 is a figure which shows the low thermal expansion linear body manufactured using the manufacturing apparatus of the low thermal expansion linear body.

図３において、１１は送り出し用ボビン１２に巻かれた負の線膨張係数を有する芯材としての繊維材料、１３はめっき槽、１４は電解液、１５はめっき槽１３内に配置されるめっき治具であり、このめっき治具１５は、第１のローラ１５Ａと、第２のローラ１５Ｂと、これらの第１のローラ１５Ａと第２のローラ１５Ｂを回転自在に支持するローラの支持軸１５Ｃとからなり、第１のローラ１５Ａと第２のローラ１５Ｂはローラの支持軸１５Ｃで支持されて電解液（例えば、Ｃｕ）１４中に浸され上下に平行に配置される。１６は正の線膨張係数を持つ導電性材料であるめっき用金属板（銅の板状体）であり、このめっき用金属板（銅の板状体）１６には＋の電圧が印加されるとともに、ローラの支持軸１５Ｃは接地線１７により接地される。１９は、図４に示すように負の線膨張係数を有する芯材としての繊維材料１１にＣｕめっき２１が施された低熱膨張線状体１８を巻き取る巻取り用ボビンである。また、２０は繊維材料１１とめっき治具１５の接触部である。   In FIG. 3, 11 is a fiber material as a core material having a negative linear expansion coefficient wound around a delivery bobbin 12, 13 is a plating tank, 14 is an electrolytic solution, and 15 is a plating treatment disposed in the plating tank 13. The plating jig 15 includes a first roller 15A, a second roller 15B, and a support shaft 15C for a roller that rotatably supports the first roller 15A and the second roller 15B. The first roller 15A and the second roller 15B are supported by a support shaft 15C of the roller and are immersed in an electrolytic solution (for example, Cu) 14 and are arranged vertically in parallel. Reference numeral 16 denotes a plating metal plate (copper plate-like body) which is a conductive material having a positive linear expansion coefficient, and a positive voltage is applied to the plating metal plate (copper plate-like body) 16. At the same time, the roller support shaft 15 </ b> C is grounded by the ground wire 17. Reference numeral 19 denotes a winding bobbin that winds up the low thermal expansion linear body 18 in which the Cu plating 21 is applied to the fiber material 11 as a core material having a negative linear expansion coefficient as shown in FIG. Reference numeral 20 denotes a contact portion between the fiber material 11 and the plating jig 15.

なお、ここで、低熱膨張線状体の製造においては、電解液が入っためっき槽内に配置されるめっき用金属板１６を正電極（電圧を印加）とし、第１のローラ１５Ａおよび第２のローラ１５Ｂは接地電極とする。   Here, in the production of the low thermal expansion linear body, the plating metal plate 16 disposed in the plating tank containing the electrolytic solution is used as a positive electrode (voltage is applied), and the first roller 15A and the second roller The roller 15B is a ground electrode.

また、第１のローラ１５Ａおよび第２のローラ１５Ｂと繊維材料１１の接触圧を高め、導通を確保するようにしている。   Further, the contact pressure between the first roller 15A and the second roller 15B and the fiber material 11 is increased to ensure conduction.

そこで、（１）まず、図２に示すように、負の線膨張係数を有する繊維材料（例えば、ザイロンまたはダイニーマ）１１を芯材として用意する。   Therefore, (1) First, as shown in FIG. 2, a fiber material (for example, Zyron or Dyneema) 11 having a negative linear expansion coefficient is prepared as a core material.

（２）次に、図３に示すように、その繊維材料１１をめっき治具１５にセットする。このとき、繊維材料１１に捩れが起こらないようにする。捩れが起こったままめっき治具１５にセットされると、単繊維の状態にめっきすることができなくなってしまうので注意が必要である。   (2) Next, as shown in FIG. 3, the fiber material 11 is set on a plating jig 15. At this time, the fiber material 11 is prevented from being twisted. If it is set on the plating jig 15 with twisting, it becomes impossible to plate in a single fiber state, so care must be taken.

（３）次いで、めっき治具１５にセットされた負の膨張係数を有する繊維材料１１をめっき槽１３に浸して、正の線膨張係数を持つ導電性材料であるめっき用金属板（例えば、銅板状体）１６をめっきする。つまり、めっき槽１３では、電着させようとするめっき用金属板１６（ここでは銅の板状体）と繊維材料１１を電解液１４中に浸す。次いで、めっき治具１５を陰極、めっき用金属板１６を陽極として、繊維材料１１とめっき治具１５の接触部２０を回転させながら直流電流を流す。すると、図４に示すように、繊維材料１１上にＣｕメッキ２１を連続的に施すことが可能になり、任意の長さの低熱膨張線状体１８が巻取り用ボビン１９に巻き取られる。   (3) Next, the metal material for plating (for example, copper plate) which is a conductive material having a positive linear expansion coefficient is immersed in the plating tank 13 by immersing the fiber material 11 having a negative expansion coefficient set in the plating jig 15. (Shape) 16 is plated. That is, in the plating tank 13, the metal plate 16 for plating (here, a copper plate) and the fiber material 11 to be electrodeposited are immersed in the electrolytic solution 14. Next, using the plating jig 15 as a cathode and the plating metal plate 16 as an anode, a direct current is passed while rotating the contact portion 20 between the fiber material 11 and the plating jig 15. Then, as shown in FIG. 4, the Cu plating 21 can be continuously applied on the fiber material 11, and the low thermal expansion linear body 18 having an arbitrary length is wound on the winding bobbin 19.

ここで、めっきを行う際の条件としては、例えば電流密度を０．５〜３．０Ａ／ｄｍ2 とする。 Here, as conditions for performing plating, for example, the current density is set to 0.5 to 3.0 A / dm 2 .

また、繊維材料１１とめっき治具１５の接触点２０の回転により移動させる繊維材料の送り速度は、１００〜３００ｍｍ／ｍｉｎとする。   The feeding speed of the fiber material that is moved by the rotation of the contact point 20 between the fiber material 11 and the plating jig 15 is 100 to 300 mm / min.

このように、この実施例では、低熱膨張線状体の製造方法として、低熱膨張特性乃至負の線膨張係数を有する、芯材としての繊維材料を用意し、この繊維材料上に、この繊維材料よりは大きな線膨張係数で正の線膨張係数を持つ導電性材料を連続的にめっきする。   Thus, in this embodiment, as a method for producing a low thermal expansion linear body, a fiber material as a core material having a low thermal expansion characteristic or a negative linear expansion coefficient is prepared, and the fiber material is formed on the fiber material. A conductive material having a larger linear expansion coefficient and a positive linear expansion coefficient is continuously plated.

なお、上記実施例では、めっき槽１３で直接めっきを行う例を示したが、あらかじめ無電解めっきを行った後に、電気めっきを行うようにしてもよい。   In the above embodiment, the example in which the plating is directly performed in the plating tank 13 has been described. However, electroplating may be performed after performing electroless plating in advance.

また、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づき種々の変形が可能であり、これらを本発明の範囲から排除するものではない。   Further, the present invention is not limited to the above-described embodiments, and various modifications can be made based on the gist of the present invention, and these are not excluded from the scope of the present invention.

本発明の低熱膨張線状体の製造方法は、トロリ線、ちょう吊線、電線、ケーブルやレールなどの線状体として利用される導電性を有する低熱膨張線状体の製造方法として利用可能である。   The method for producing a low thermal expansion linear body of the present invention can be used as a method for producing a low thermal expansion linear body having conductivity used as a linear body such as a trolley wire, a hanging wire, an electric wire, a cable or a rail. .
